Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, and more specifically, to a mine tunnel deformation measuring device. Background Technology

[0002] In mining operations, tunnel stability directly impacts mining safety and efficiency. As mining depth increases, the geological pressures faced by the tunnel become more complex, significantly increasing the risk of deformation. During deep mining, the self-weight stress and tectonic stress of the surrounding rock intensify, leading to increased rock pressure and accelerated deformation, seriously threatening the safety of underground personnel and mine production. Therefore, accurate and efficient measurement and monitoring of tunnel deformation is crucial for ensuring safe mine production. Currently, various tunnel deformation measurement devices are available on the market. Some devices use multiple sensors mounted on a frame to measure tunnel deformation. However, this traditional design has significant drawbacks. Because the sensors are fixedly installed, measurements can only be taken at a few specific points, inevitably creating measurement blind spots between sensors. This greatly reduces the accuracy of the measurement results and fails to comprehensively and accurately reflect the actual deformation of the tunnel. Moreover, the use of multiple sensors significantly increases the overall cost of the device, raising equipment procurement and maintenance costs for mining companies. Therefore, improvements are needed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a mine tunnel deformation measuring device, comprising:

[0022] A fixed frame 1 has a groove 2 on its outer surface. A round shaft 3 is movably fitted inside the fixed frame 1, and a driven toothed pulley 4 is fixedly fitted on the outer surface of the round shaft 3. A drive mechanism is located at the bottom of the left side of the front of the fixed frame 1. A measuring mechanism is located on the outer surface of the fixed frame 1. The measuring mechanism includes a slide rail 5, which is fixedly connected to the outer surface of the fixed frame 1. A slider 6 is slidably connected inside the slide rail 5. The outer surface of the slider 6 is slidably connected to the inside of the groove 2. A round rod 7 is fixedly installed on the outer surface of the slider 6. The outer surface of the round rod 7 is slidably connected to the inside of the slide rail 5. A moving plate 8 is fixedly installed at the end of the slider 6 away from the fixed frame 1. An ultrasonic transmitter 9, an ultrasonic receiver 10, and a transducer 11 are respectively provided on the moving plate 8.

[0023] The drive mechanism provides power to move the measuring mechanism along the fixed frame 1, enabling deformation measurement at different locations in the mine tunnel. The measuring mechanism collects relevant data on mine tunnel deformation. The slide rail 5 is fixedly connected to the fixed frame 1, providing a track for the slider 6 to slide. The slider 6 cooperates with the slide groove 2 and the slide rail 5 to slide along the fixed frame 1, and the round rod 7 fixed on its outer surface slides within the slide rail 5, further enhancing the stability of the slider 6's sliding. The motion plate 8 integrates and mounts the ultrasonic transmitter 9, ultrasonic receiver 10, and transmitter 11. The ultrasonic transmitter 9 emits ultrasonic waves to detect the mine tunnel wall, and the ultrasonic receiver 10 receives the reflected waves. Together, they acquire mine tunnel deformation information. The transmitter 11 sends out the measurement data for external receiving devices to acquire.

[0024] The drive mechanism includes:

[0025] The back of the motor 12 is fixedly connected to the bottom of the left side of the front of the fixed frame 1, and the output end of the motor 12 is fixedly sleeved with the rotating shaft 13; the drive toothed pulley 14 is fixedly sleeved with the outer surface of the rotating shaft 13, and the drive toothed pulley 14 is connected to the driven toothed pulley 4 through the toothed belt 15, and the outer surface of the toothed belt 15 is fixedly connected to the slider 6.

[0026] The motor 12 serves as the power source, with its back fixedly connected to the bottom left side of the front of the fixed frame 1. It outputs power through the rotating shaft 13, which is fixedly sleeved at the output end, driving the drive toothed pulley 14 to rotate. The drive toothed pulley 14 is connected to the driven toothed pulley 4 via a toothed belt 15, transmitting the power of the motor 12 to the driven toothed pulley 4, thereby driving the toothed belt 15 to move. The outer surface of the toothed belt 15 is fixedly connected to the slider 6, thus driving the measuring mechanism to move.

[0027] The fixed frame 1 has a fixed shaft 16 fixedly installed inside, and a roller 17 is movably sleeved on the outer surface of the fixed shaft 16. The outer surface of the roller 17 is in contact with the toothed belt 15.

[0028] A fixed shaft 16 is fixedly installed inside the fixed frame 1 to provide a mounting shaft for the roller 17. The roller 17 is movably sleeved on the outer surface of the fixed shaft 16, and its outer surface contacts the toothed belt 15, which supports and guides the toothed belt 15 to ensure the stability of the toothed belt 15 during transmission.

[0029] Among them, a conductive block 20 is fixedly installed on the outer surface of the motion plate 8, and a limit rail 18 is slidably connected to the outer surface of the conductive block 20. The outer surface of the limit rail 18 is fixedly connected to the outer surface of the slide rail 5.

[0030] Due to the design of the limiting track 18, it not only provides a sliding track for the conductive block 20, but also plays an auxiliary limiting role in the movement of the motion plate 8, thereby enhancing the stability of the movement of the motion plate 8.

[0031] The limiting track 18 has a conductive rod 19 inside, and the outer surface of the conductive rod 19 abuts against the outer surface of the conductive block 20.

[0032] The limiting track 18 is equipped with a conductive rod 19 inside, which serves as a carrier for power transmission. Its outer surface abuts against the outer surface of the conductive block 20, ensuring that the conductive block 20 and the conductive rod 19 remain in continuous contact during the movement of the moving plate 8, so as to stably transmit power to supply power to the ultrasonic transmitter 9, ultrasonic receiver 10 and transmitter 11.

[0033] The fixed frame 1 has a fixed block 21 installed inside it. The fixed block 21 is equipped with a dustproof brush 22, which abuts against the surface of the slider 6.

[0034] A fixing block 21 is fixedly installed inside the fixing frame 1 for installing a dustproof brush 22. The dustproof brush 22 is set on the fixing block 21 and abuts against the surface of the slider 6. When the slider 6 slides along the fixing frame 1, the brush blocks the dust in the mine channel from entering the device through the gap between the slider 6 and the fixing frame 1, protecting the internal components from dust pollution and maintaining the stable operation of the device.

[0035] Working principle and usage process of this utility model:

[0036] When using the mine tunnel deformation measuring device of this invention, the operator first energizes the conductive rod 19. The current is transmitted through the conductive rod 19 to the conductive block 20, and then through wires to power the ultrasonic transmitter 9, ultrasonic receiver 10, and transmitter 11 on the moving plate 8, putting them into working condition. At this time, the ultrasonic transmitter 9 emits ultrasonic waves towards the mine tunnel wall. After the sound waves are reflected by the wall, they are captured by the ultrasonic receiver 10. After being analyzed by the internal signal processing system, the data is transmitted to the transmitter 11, and finally sent to the operator's mobile terminal and control center, realizing the acquisition and transmission of local deformation data of the mine tunnel.

[0037] To obtain overall deformation data of the mine tunnel, the operator starts motor 12. The motor output shaft drives the rotating shaft 13 to rotate, which in turn drives the toothed pulley 14 to rotate. The toothed belt 15 drives the driven toothed pulley 4 to rotate synchronously around the circular shaft 3. During this process, the fixed shaft 16 and roller 17 in the fixed frame 1 work together to provide stable support and guidance for the toothed belt 15. As the toothed belt 15 is driven, the slider 6, which is fixedly connected to it, slides along the groove 2 and the arc-shaped slide rail 5 of the fixed frame 1, conforming to the arc-shaped contour of the fixed frame 1. Because the fixed frame 1 is an arc-shaped structure adapted to the mine tunnel space design, the slide rail 5 is arranged in an arc shape with the fixed frame 1. Under the traction of the toothed belt 15, the slider 6 moves along the arc-shaped trajectory of the fixed frame 1, relying on the guidance of the slide rail 5. This drives the motion plate 8 and the ultrasonic transmitter 9, ultrasonic receiver 10 and transmitter 11 mounted on it to move synchronously, realizing the arc-shaped traverse scanning measurement of the mine tunnel wall and accurately obtaining the overall deformation data of this section of the mine tunnel.

[0038] In addition, the dustproof brush 22 on the fixing block 21 inside the fixing frame 1 is closely attached to the surface of the slider 6. During the operation of the device, the brush blocks and isolates the dust in the mine channel from entering the device through the gap of the slider 6 movement, thereby reducing the pollution and interference of dust on the internal transmission and measuring components, ensuring the stable operation of each component and maintaining the measurement accuracy.
